Frozen dessert is the generic name for desserts made by freezing liquids, semi-solids, and sometimes even solids. They may be based on flavored water (shave ice, ice pops, sorbet, snow cones, etc.), on fruit purées (such as sorbet), on milk and cream (most ice creams), on custard (frozen custard and some ice creams), on mousse (semifreddo), and others. In the UK and Ireland, frozen desserts are referred to as "ices".
In Canada and elsewhere, the term is often used on imitations of ice cream which do not satisfy its legal definition (e.g., mellorine).
